powerpc/oea: trap: pmap_{pte,ste}_spill() even in the interrupt context

Page table for oea is something like L2 TLB on memory; kernel and
processes share its entries, and process entries can be spilled out.

As done for MMU based on software-managed TLB, we need to restore
such entries even in the interrupt context.

Note that pmap_pte_spill() require no resouce to restore entries.
Still-not-implemented pmap_ste_spill() for OEA64 should also.

powerpc/oea: pmap: Fix mostly-pointless overhead of pmap_pvo_pool
(1) Drop __aligned(32) from struct pvo_entry; otherwise,
    sizeof(struct pvo_entry) is round-up'ed to a multiple of 32.
(2) Do not set sizeof(struct pvo_entry) to `align` argument for
    pool_init(9); it must be power of 2.
(3) Align pvo_entry to 32-byte boundary only if reasonably possible,
    i.e., OEA without DIAGNOSTIC (--> POOL_REDZONE) for now.

powerpc: Sprinkle "memory" clobbers on eieio and nearby asm blocks.

Otherwise the compiler may reorder these around loads and stores,
which mostly defeats the purpose.  `asm volatile' just ensures the
instruction isn't _deleted_; it may still move around.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
